Buzzer manufacturer: two applicable methods of piezoelectric buzzer

2020-11-02

Buzzer manufacturers piezoelectric buzzer and unique buzzer is not the same, piezoelectric buzzer whether from the characteristics, into the category or the price above all have the advantages can not be compared.

The driving principle of electromagnetic buzzer?

2020-10-26

The electromagnetic buzzer I .e. the principle of current flow through the solenoid, the field diaphragm solenoid drives the sound. Therefore, it is necessary to determine the current power. The current of the microcontroller output voltage is small, and the TTL level output from the drive system of the monolithic buzzer requires a large circuit. The S51 enhanced MCU is implemented by a buzzer driver board and an amplifier transistor C8550.

SMD buzzer introduces the structure of electromagnetic buzzer knowledge?

2020-10-25

Iron core: mainly divided into two kinds of processing technology: stamping and die casting. The material is an iron-nickel coating. The reason for choosing iron is that the magnetic permeability is better, and nickel plating is added to achieve the purpose of rust prevention. The core buzzer is mainly used as a support for PCB, magnetic permeability and gap control actions, so the height and dimensional accuracy of the core are high, and the overall tolerance is controlled within ± 0.01mm.

SMD buzzer introduces the correct use of electromagnetic buzzer method?

2020-10-22

There are many types of buzzers on the market, but different types of buzzers have different prices and quality. If you want to buy a high-quality electromagnetic buzzer, you need to choose a suitable buzzer, which is the problem of use.

SMD buzzer tells the production process of electromagnetic buzzer?

2020-10-22

The electromagnetic buzzer is composed of an oscillator, an electromagnetic sensor coil, a magnet, a diaphragm that affects vibration, and a housing part. When energized, the audio signal generated by the oscillating current flowing through the electromagnetic coil generates a magnetic field. The diaphragm periodically vibrates when interacting with the electromagnetic coil of the magnet.

SMD Buzzer Small Class Explanation: Several Types of Failure Causes of Instrument Types?

2020-10-20

We must have seen the instrument buzzer in the car, and the place where the car is used is different, the size and the size are different, the prompt sound and the reversing buzzer are very different. In fact, after they have been used for a period of time, there will be faults that can be large and small. At this time, we need to analyze their data and effectively solve the management according to different faults.
